Thickness, Parallelism and Flatness Precision Grinding, Inc.

Some drawings ask for a part to be flat in the restrained condition. This is not true flatness but the surface is intended to be flat enough to be bolted or clamped in a flat condition. Normally, if a flatness of 0.003″/ft is quoted, then multiply the diagonal dimension of the part in feet by 0.003″ to get the total flatness tolerance.

Flatness – GD&T Basics

Flatness tolerance is always less than the dimensional tolerance associated with it. Tolerance ZoneTwo Sets of Parallel Planes where the entire referenced surface must lie. Gauging / MeasurementFlatness is can be measured using a height gauge run across the surface of the part if only the reference feature is held parallel.

Jan 12, 2007 · If you don't care about final flatness just go for it. You can get the thing real parallel without being flat. As for mill straightness, it may be in tolerance, but is unusually bent. Most A36 that I've used was straight to .005/foot. But I have recieved some that was so crooked it wouldn't work in a automatic band saw.

Flatness Tolerance Accurate Perforating

Flatness Tolerance. The charts below show the maximum deviation from a perfectly horizontal flat surface. A ruler that does not flatten the material has been used to measure the amount of flatness. The measurement is taken from the highest point (or points) of the sheet or plate to the table surface minus the material thickness.

Flatness Engineering Essentials

Flatness ControlPerfect flatness is when all points of a surface lie in the same plane. Flatness is a form control. The flatness control (c) defines how much a surface on a real part may vary from the ideal flat plane. Tolerance ZoneThe flatness tolerance zone is the volume between two parallel planes.
